In the fall of 1925, representatives of the powers which had attended the Washington Conference met in Peking for the long-delayed discussion of China's claim to tariff autonomy. Germany was not one of this group and received no special invitation; however, the Germans hoped that they would be allowed to participate, especially since in European affairs they had been given a place of equality in the October Locarno Conference. Consequently, as a step in this direction, Berlin readily accepted an invitation from the United States to adhere to the Nine-Power Treaty of the Washington Conference. To the surprise of both countries, China took offense. This episode, which passed almost unnoticed behind the scenes of the Tariff Conference, revealed Germany and the United States pursuing somewhat similar policies against which the Chinese foreign minister protested. It disclosed Chinese suspicion and distrust, not only of their policies, but of the Nine-Power Treaty as well.
